LAMP-STAND BODY.

Specification 0t Letters Patent.

Patented J une 8, H915.

To all whom, it may concern:

Be it known that we, VVILLIAM A. MCKAY and MARTIN CLAUSSEN, subject of the King of Great Britain and citizen of the United States, respectively, residing at San Francisco, county of San Francisco, and State of California, have invented new and useful Improvements in Lamp-Stand Bodies, of which the following is a specification.

The present invention relates to improvements in bodies for incandescent lamp stands and the like.

In an application for United States Letters Patent, filed by us Feb. 11, 1913, Serial No. 747,670, we disclose an incandescent electric lamp having a hollow body, having a concave bottom, and a wire clamp concealed in the bottom of the body, and having vertical extensions through said body around which are coiled springs which normally press the wire clamp to the body, and thus furnish a means for enabling the edge of the table or the like to'be gripped between said clamp and the body. Said body comprises upper and lower plates or disks, spaced by a cylinder, and in said application we disclose means for securin said plates together, consisting of tubes anged at the upper ends and whose lower ends are screw threaded and screwed into holes in the lower plate.

The object of the present invention is to provide a simpler and cheaper construction for accomplishing this result.

In the accompanying drawing, Figure 1 is a vertical section of our improved lamp body: Fig. 2 is a perspective view of a. tie bar, detached; Fig. 3 is a bottom plan view of the lamp.

Referring to the drawing, 1 indicates an upper plate, 2 an intermediate plate, and 3 a lowermost plate of a lamp body. Upon the upper plate 1 is secured a forked standard 4 for supporting a socket 5 of aii electric lamp. Between the intermediate and upper plates 2, 1, is interposed a cylinder 6 upon which the lamp cord 15 can be woun said cylinder servin to space said plates 1, 2, and the edges 0 the intermediate and lower plates clamp between them a rubber ring 7. The plates 1 and 3 are formed with registering oblong holes 10 and through said holes are passed straight tie bars 8, more particularly shown in Fig. 2. Said tie bars are preferably concavo-convex transversely of their length. The terminal portions of the tie bars are bent at right angles, the lower terminal portion 9 of each tie bar being of the same width as the bar proper, and having a round hole 11. The upper terminal portion 12 of each tie bar is enlarged in width, and has a round hole 13 somewhat larger than the hole 11, and a short cylinder 14 depending from the margin of the hole 13. The lower portion 9 of the tie bar is sufliciently small to pass through the oblong holes in all the plates, but the upper portion is too large to pass through said holes. When the tie bar is passed through the upper plate downward, said portion 12 rests against said plate 1, and the short cylinder 14 extends through the hole 13. When the tie bar has been passed through both of said plates in the manner above indicated, the lowermost plate is pressed toward the upper plate so that a space intervenes between said lowermost plate and the lower portion 9 of the tie bar. \Vhile the parts are in this position a washer 16 is inserted between said lower portion 9 and the lower plate 3, and pressure is then removed from said lower plate 3, whereupon the washer is firmly compressed between said lower plate and the lower portion of the tie bar. The pressure on said washer is so great that it can only he removed by considerable force. By this means, therefore, the plates are all firmly secured together. Said washer is formed with a hole 17 which registers with the hole 11, and these holes, and the hole 13 in the upper extension, thus form a guide for a vertical member 18 of a wire clamp 19.

Ne claim A support for lamps and the like comprising apertured plates, a movable rod, and

means for securin together said plates spaced from each ot er and for guiding said rod through sald plates comprising a tie member having an apertured part at one end set our hands in the presence of two Sus too large to pass through a hole in one of scribing witnesses.

the glates and at the other end an aper- WILLIAM MCKAY ture part sufficiently small to pass throu h 4 a hole in the other plate and an aperturzd MARTIN CLAUSSEN washer inserted between said latter part and Witnesses: plate. F. M. WRIGHT,

In testimony whereof we have hereunto D. B. RICHARDS.
